Title: Screw head structure
IPC: B29C45/52
Filed: 1992-03-26
Abstract: PURPOSE:To prevent resin baking and wear between a non-return ring and a screw head. CONSTITUTION:A non-return ring 2 is arranged on an outer periphery of a small-diameter part 1c of a screw head 1, and a resin passage 21 is formed. A wing 23 is formed from the rear toward the front of the head 1 at the head 1. The wing 23 is so inclined that its front end becomes forward in a rotating direction of a screw 4 at the time of weighing and its rear end becomes rearward in the rotating direction. In this case, when an angle formed between a surface including the wing 23 and an axis of the screw 4 is theta, 5 deg.<=theta<=60 deg. is satisfied. If the ring 2 is moved forward when the screw 4 is moved backward, the wing 23 is rotated together with the head 1, resin is pushed back upon rotation, and a retreating force is generated at the ring 2 so that both are not brought into contact with one another.

Title: Image pickup device
Inventor: YAMADA EIJI
IPC: H04N5/349
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a high resolution image with less color moire and excellent image quality. SOLUTION: An image light from an object passes through an optical system 63 and through each filter element of a color filter provided to a light incidence side of a solid-state image pickup element 64. The filter element passes through 1st to 4th color lights among image lights and the lights are made incident on a corresponding light receiving area of the element 64. The element 64 is a 2-picture element hybrid read element, which provides an output of an original image signal consisting of mixed data corresponding to the quantity of the two color receiving lights. In the usual mode, a signal processing circuit 74 generates a single output image from a single original image signal. In the high resolution mode, tilt image shift is conducted to an image forming position of the image light in parallel to four positions in the tilt direction.  Every time the image forming position is moved by image shift, the element 64 picks up the image light. The circuit 74 generates a single output image from the four original image signals picked up at the different image forming positions.

Title: Method for detecting mount position of position detector
Inventor: NISHIZAKI JUNICHI
IPC: G01B11/00
Filed: 1989-03-23
Abstract: PURPOSE:To accurately calculate the mount position and angle of inclination of a position detector using the reduced number of stripes by horizontally arranging a calibration plate having a stripe pattern so that said stripe pattern is positioned within the visual field of a television camera and measuring the length from a reference position to the boundary line of the stripe pattern. CONSTITUTION:A television camera 1 receives the image of a calibration plate 2 and the xj signal of the detection value at each point Pj is sent to a position operator 4. On the assumption that position detection values xj are scattered within a range of + or -N pixels from the number of photodetectors, a function f(xj, x, y, alpha) is formed and x, y and alpha minimizing an evaluation function Q1 represented by formula I are calculated. By this method, since a mount position and an angle alpha of inclination are calculated on the assumption that the detection values of the television camera are set with due regard to the irregularity to a real value, the mount position and angle of inclination of the television camera being a position detector can be accurately calculated using the reduced number of stripes. In the formula, M is the boundary line number of the stripe pattern, N is the number of pixels scattered in detection values and Rj is the measured length from a reference position to the j-th boundary line.

Abstract: PURPOSE:To carry out a circuit test without causing damages to other circuits, by branching and inserting the call/control signal relating to a channel that is desingated optionally among the digital multiplex circuits and by giving a by-passing to other channels. CONSTITUTION:Both the time-division switch TDSW side and the transmission line side are led into the side of the DTI test device TSTE simultaneously via test relay contacts t1 and t2 between a device DTI which terminates the digital multiplex circuit to a time-division digital exchange and the multiple transmission line.

Title: Single-plate color solid-state area sensor
Inventor: TANAKA SHOICHI
IPC: G01J3/50
Filed: 1984-04-06
Abstract: PURPOSE:To improve resolution by arranging an yellow, a green (or white), a cyan, and a white (or green) picture element in this order. CONSTITUTION:Picture elements of yellow(Ye), green(G), cyan(CY), and white(W) are arrayed in each row in this order. Consequently, reduced components of a signal of each picture element row becomes a brightness signal approximately and a signal difference between two horizontally adjacent picture elements generates a red(R) signal and a blue(B) signal alternately. Consequently, a color separating circuit becomes extremely simple and dichroic separation is not performed by utilizing vertical correlation, so the resolution of a powerful G signal is improved. Then, N adjacent picture elements and N+ or -1 (or N+ or -2) picture elements are shifted preferably and horizontally by two picture element pitches. Consequently, a decrease in vertical brightness resolution is suppressed and horizontal resolution is improved.
